Overview of the Schneider 140CPS12400 Power Supply Module

The 140CPS12400 delivers regulated power to Modicon Quantum PLC racks and connected I/O modules. This unit converts AC mains input into stable DC output for continuous control operations. Engineers rely on it in process plants that demand uninterrupted, clean power delivery.

Key Technical Specifications of the 140CPS12400

The 140CPS12400 combines a rugged housing with a backplane mounting interface. Below you will find the core parameters that define this module’s performance envelope.

Physical Design and Interface Details

The 140CPS12400 adopts a compact footprint that fits standard Quantum backplanes. Its dimensions measure 140 mm in length, 105 mm in width, and 40 mm in depth. Moreover, the module weighs roughly 450 grams, which simplifies rack installation and field replacement. The backplane connector distributes power directly to adjacent modules.

Performance and Power Delivery Capabilities

This module accepts 100–240 V AC input across a 47–63 Hz frequency range. It delivers 24 V DC regulated output at up to 8 A, therefore supporting full rack loads. Overvoltage and short-circuit protection safeguard connected modules from electrical faults. Additionally, the unit supports redundant configurations for high-availability architectures. Consequently, it suits critical control applications in automated plants.

Environmental Considerations

The 140CPS12400 operates reliably from 0°C to 60°C in industrial settings. Storage temperature extends from -25°C to 70°C without performance loss. Furthermore, humidity tolerance reaches 95% RH without condensation forming. These ratings keep the module stable across demanding plant floors.
